摘要：
This paper presents a three-dimensional model of two-stage straight bevel gear system. Periodic fluctuations of the gear meshes' stiffness are the main sources of excitation for the faultless gear system. First, dynamic response is calculated using Newmark method which is step-by-step time integration. The numerical results are presented in both the frequency and time domains. After that, we introduce some defects in the developed model such us the eccentricity defect, profile error and cracked tooth. The dynamic behavior of the defected gear system is compared with that of the faultless system. The numerical results from this work have applications in the design phase or maintenance of this type of bevel gear transmission. (C) 2014 Elsevier Ltd. All rights reserved.
